The 2014 South Coastal Maine Rarity Roundup

For the past ten years, I have organized the “South Coastal Maine Rarity Roundup” on the first weekend of November, when a group of friends get together to comb the coast from Kittery through Portland, focusing on finding lingering migrants, rarities, and hopefully “mega” vagrants.

This year, our event was postponed a week thanks to the massive Nor’easter and snowstorm that rendered last Sunday essentially un-birdable. A week later than usual, we expected fewer birds, but perhaps “better birds.” At the very least, we would be less miserable than in the 34-degree weather with driving wet snow and 50mph winds of last Sunday. Recent active weather and some good birds in the area helped stoked our “rarity fever” fire, which I prognosticated about on Friday’s blog.

Although most teams described the day as “fairly slow” overall, we did indeed find some good birds, and surprisingly good diversity. 121 species (plus two subspecies) were recorded in all, well above the 11-year average of 114 species. Two new species were added to the all-time Rarity Roundup list: American Redstart and Lincoln’s Sparrow. Meanwhile, Brown Creeper went unrecorded for the first time, likely a factor of the scrubby habitats and open areas that we focus on at this time of year.

Unfortunately, despite overall high-quality birds, we once again failed to turn up any “mega” rarities. However, we did have a lot of fun as always, which really is the most important part. Or so we tell ourselves.

My guess is the later date this year helped those Harlequin Duck, Purple Sandpiper, and Lapland Longspur totals, and perhaps also the higher counts of Ruddy Ducks and American Coots. An overall mild fall likely resulted in the late departure of so many “half-hardies” such as Ruby-crowned Kinglets, Hermit Thrushes, and Chipping Sparrows. And the steady increase of Red-bellied Woodpeckers continues.

So not bad, and once again it gives us a fascinating snapshot into the under-birded late fall season along the southern Maine coast.

Personally, I was joined by friends as usual in Portland. While Jeannette (and Sasha) birded Capisic Pond Park, Evergreen Cemetery, and Back Cove, Kristen and Evan joined me on my march through the Portland peninsula. Jeannette gets the territory’s bird-of-the-day honors with the First Rarity Roundup Record Lincoln’s Sparrow at Capisic Pond Park, where she also had the count’s only Common Yellowthroat.

The peninsula, however, was about a slow as I have ever experienced it on a Rarity Roundup, likely due to the later date and resultant fewer food supplies. But even still, the Eastern Promenade was uncharacteristically slow, and development and ridiculous bush-whacking and clear cutting by the City of Portland diminished the value of the habitat along West Commercial Street.

With a few interesting birds, including our best bird of the day, a Red-eyed Vireo in a front yard in the West End, I wish I had gotten to this neighborhood sooner in the day, but alas, hindsight is always 20/20. And while Portland’s overall performance paled in comparison to the hauls from recent years, we still had some great birds. The flock of 60-75+ White-winged Crossbills that flew over us on the Eastern Promenade were the first I have seen all year, the pair of Northern Shovelers in Deering Oaks Park were unexpected, and the 4 immature Black-crowned Night Herons at Mercy Pond were good to see.

But perhaps the bird of the day was the Hermit Thrush. We had an impressive total of 31 throughout our day, including several in small downtown gardens and landscaping corners. White-throated Sparrow (including 24 scattered around downtown as well) were also prevalent. These two species were the only native birds – as usual – that we found in the center of downtown Portland. This always fascinated me, as these two species seem particularly regular in the heart of concrete jungles.I think this phone-photo of a Hermit Thrush captures the essence of this intriguing topic of conversation.

Perhaps next year we will find the “next big one.” Until then, I have some more fun data to play with.
